Climate change is a change in global or regional climate patterns attributed to increased levels of carbon dioxide from fossil fuel use since the mid-20th century. According to NASA, there has been a rise in CO2 levels and global temperatures, and decreases in Arctic ice and land ice. While past climate changes have occurred, current warming is happening much faster than past events due to human activities like burning fossil fuels that release greenhouse gases into the atmosphere. Effects of continued warming may include more extreme weather, droughts, sea level rise, and damage costs increasing over time. Individual actions like using less energy and driving less can help address climate change along with efforts of environmental groups.

1. Rise in temperature

2. What is Climate Change ?
A change in global or regional climate patterns, in
particular a change apparent from the mid to late 20th
century onwards and attributed largely to the
increased levels of atmospheric carbon dioxide
produced by the use of fossil fuels. According to
NASA, there has been :
 Increase in CO2 by 404.42 ppm
 Increase in Global Surface Temperature by 1.7○
 Decrease in Arctic Ice by 13.3% per decade
 Decrease in Land Ice by 281 gigatonnes per year

3. How is today’s warming different ?
Earth has experienced climate change in centuries
past. The chemical make-up of ice provides clues to the
average global temperature. The paleoclimates along with
global models shows ice ages and periods even warmer
than today. But the paleoclimate record also reveals that
the current climatic warming is occurring much more
rapidly than past warming events.

5. Whose Contribution Is It ?
 Earth has a natural “blanket” of gases around it, the greenhouse
gases, which keeps the Earth’s temperature an optimum.
 Since the Industrial Revolution, due to various human
activities, the amount of greenhouse gases has rapidly
increased causing a continuous increase in the Earth’s
temperature.
 This temperature increase along with other factors like solar
input, volcanism, plate tectonics etc. leads to climate change
 Thus, in the end it is us Humans who are to be blamed.

6. Effects
In the next century or so,
 Temperatures will continue to rise. It is predicted to rise almost
3-10 degrees.
 There will be increased frost-free or growing seasons.
 Changes in precipitation pattern can be seen.
 There will be more droughts and heat waves.
 Occurrence of stronger hurricanes and related rainfall.
 Sea level will increase by almost 1-4 feet.
 Arctic is likely to become ice free, mid century.
Taken as a whole, the range of published evidence indicates that the net
damage costs of climate change are likely to be significant and to
increase over time.

7. YES NO
 Plant Trees
 Recycle inorganic and compost
organic waste
 Carpooling with co-workers
 Public transport
 More natural ventilation and
less of hoarding.
 Natural and organic farming
 Natural air fresheners and less
perfumes.
 Renewable energy sources- GO
GREEN !
 Cut down trees
 Burn waste
 A car per person
 Private transport
 More AC ‘s and Refrigerators
 Chemicals in fertilizers and
pesticides.
 Chemicals in air fresheners and
perfumes.
 Fossil fuel run vehicles and
industries

8. What can be done
 The 4 R’s –Reduce, Reuse, Recycle, Recover.
 Instead of private use public transport.
 Start carpools rather than individual transport.
 PLANT TREES !
 Organic and natural farming.
 Eat less meat.
 Renewable sources of energy.
 Energy efficient appliances.
 Awareness programs –Street plays, Rallies etc.

9. Who’s fighting ?
 350.org is a website which unites activists from all over
the world to fight climate change. Its main aim is to keep
use of carbon at bay.
 Sierra club in the USA along with conservation of their
wilderness, they also protect the habitats thus saving the
environment.
 Greenpeace whose main goal is to maintain our
biodiversity and also works against climate change etc.
 People’s Climate March of 2014 was a large-scale activist
event to advocate action against climate change.
